ADJUSTABLE DOOR-JAMB.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed March 17,1905. Serial No. 250,541.

To all whom it may concern.-

Be it known that I, JOHN R. CoRBIN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn,

in the county of Kings and State of New struction of jamb it is often necessary to trim or plane the face of the door in order that the door may close without difficulty,

and this is especially true in the case of a new door. It is my intention, therefore, to con struct a door-jamb with a movable strip and provide certain means whereby part of the jamb may be adjusted relative to the door, so that it will be unnecessary to trim or otherwise change the structure of the parts after they have once been placed'in position.

To the accomplishment of these ends my invention consists in the construction, combination, and arrangement of parts set forth in and falling within the scope ofthe appended claims.

' While I have shown and described a preferred embodiment of my invention as applicable to a door, I wish it to be understood that I do not confine myself to all the precise details of construction and application which for the purpose of illustration I have delineated, as there may be modification and variation in some respects without departing from the spirit or scope of the claims.

In the accompanying drawings like characters of reference indicate like parts in all the views.

Figure 1 is a transverse horizontal sectional view taken through a door-jamb provided with my improvement, such view also showing a portion of the door. Fig. 2 is a similar view taken through the part of the jamb provided with the adjustable strip and Figs. 3, 4, and 5 show detail views of the adjustable dev1ce.

Referring now to the accompanying drawings in detail, and particularly in Fig. 1, 5

indicates an ordinary vertical stud, and 6 6 indicate the ordinary casing-strips, each of said casing-strips having a groove 7 out therein to receive a tongue 8 of the doorjamb 9. 10 is a pocket formed by the casings, the stud, and the door-jamb. The door-jamb 9 is formed with a vertical groove 11, extending the length of one side thereof, into which groove is adapted to fit the adjustable strip 12. The groove is cut slightly larger than the strip, so that a space 18 is left to permit of the adjustment of the strip, as hereinafter described. Through approximately the center of this strip is bored or cut a transverse aperture 14 in line with a similar channel or aperture 15, cut in the portion 16 of the door-jamb. Into such alining openings is adapted to be fitted the adjusting device, of which the following is adetailed description. This device comprises in its construction a relatively long screw-bolt 17, adapted to pass through a two-part sleeve member composed of the separable parts 18 and 19. As will appear from the drawings, these members are tubular and the member 19, which I will hereinafter term the head member, comprises an enlarged flanged head portion 20 and a shank portion 21, said shank being formed with a number of spiral twistthreads or ribs 22. Into the head portion is countersunk the head 17 a of the screw 17, said screw being retained in place against longitudinal movement by an inwardly-extending annular flange 23, which may be in the nature of a washer welded into said head portion and flush with the upper surface there'- of. The lower extremity of the shank of such head portion is formed with a cross-slot 24, adapted to receive the shouldered end 25 of the sleeve member 18, which member is also formed with a number of spiral ribs or threads running longitudinally of its body portion. At its lower end such sleeve member is formed with a reduced portion 26, approximately circular in cross-section, so that a smalls uared shoulder 27 is formed, which shoulder ears against the projecting portion 28, formed in the j amb of the door by the bore extending therethrough.

The parts may be assembled and placed in position while in the workshop, and the jamb when it is ready to be set up in the building ordwelling has substantially the appearance in cross-section as shown in Figs. 1 and 2. If it be found that the door does no fit properly and it is desired to adjust the jamb, it is only necessary to turn the screwbolt with a screw-driver or the like and the adjusting-strip 12 will be moved toward or from the jamb, as the case may require. When the screw is turned toward the right, the parts 14 and 18, being held against movement by the ribs or spiral threads, the adjusting-strip must necessarily be drawn in toward the jamb, while when such screw is turned toward the left such strip will be loosened and spring outwardly.

[ The many advantages incident to my improved door-jamb and adjusting means will be readily apparent. Aside from the fact that it is unnecessary to trim or plane the edge of the door, it will be noted that the parts may all be assembled at the shop and when in position at the building will enable any one by simply turning the screw to adjust the jamb as occasion may require, thereby compensating for shrinking and the like. In an ordinary door I preferably employ four of the adjusting devices in connection with the jamb-strip, so that the strip may be uniformly adjusted its entire length.

In Fig. 1 the door is shown at A, and the adjustable strip of the jamb is so arranged that the door is shown as fitting snugly against the same without binding.

In the present drawings I have shown my invention employed in connection with a door, but it is equally as applicable to a windowsash, drawerslide, pulley, stile, and similar constructions, and 1 do not limit my self to the precise application of the invention which 1 have shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a door-jamb or the like, of a movable strip therefor, and means for adjusting said strip relative to the j amb, such means comprising two members, one secured against rotation in the jamb and the other secured against rotation in the strip, said members being in alinement and having abutting end portions, and a rotating element connecting the two members.

2. The combination with a door-jamb, or the like, of a movable strip mounted in a groove cut in said j amb, said strip having a bore extending therethrough in alinement with a similar bore cut in the jamb, a sleeve member fixedly retained in each bore, and a rotatable element extending through both sleeve members whereby through the rotation of said element said strip may be tightened or loosened in the grooves of the j amb.

3. The combination with a jamb, of a strip designed'to be secured thereto, and a device for permitting the adjustment of said striprelative to the jamb, comprising two sleeve portions arranged end to end, a screwrod extending through said sleeve portions but held against longitudinal movement relative thereto, and means for locking one of said sleeve portions to the other.

4. An adjusting device for jambs and the like, comprising a strip portion, a tubular sleeve portion embedded in said strip and having a lateral slot cut transversely across the base thereof, a second sleeve portion provided' with a reduced shoulder at the end thereof-designed to engage said slot, and a screw-rod extending through the sleeve portions and designed to project into the jamb.

5. An adjusting device for jambs and the like, comprising a tubular sleeve portion, a second sleeve portion abutting end to end and adapted to interlock with the first sleeve portion, a screw-rod having its head countersunk in the head of the first-mentioned sleeve portion, and an inwardly-extending flange projecting over the head of the screw-rod to hold such screw-rod against longitudinal movement.

6. The combination with a jamb, of a sleeve portion arranged in a bore formed in said jamb, a second sleeve portion embedded in an adjustable strip arranged adjacent to the jamb, and held against rotation, and adapted to abut end to end with the firstmentioned sleeve portion, and a screw-rod extending through and connecting said sleeve portion substantially as set forth.

7. An adjusting device for j ambs, and the like, comprising a strip, an exteriorly-threaded tubular sleeve extending through said strip, an exteriorly-threaded sleeve extending through the jamb, and a rotatable element passing through both of said sleeves.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN R. CORBIN.
